1 This is the edition of Buflfon that Boddaert cites all throtigh his " Table des Planches 

 EnluminSez d'Histoire Naturelle de M. d'Aubenton." The portion of this edition (18 vol- 

 umes) relating to birds appeared from 1770 to 1785. In my recent paper on Butorides 

 virescens (Proc. U. S. Nat. Mus., vol. 42, 1912, pp. 533 and 564), I inadvertently credited 

 two of Boddaert's references to the Deux Ponts edition, which references should, of course, 

 read " ed. Montbeillard." Suckow, however, in his "Anfangsgrunde der theoret. und ange- 

 wandt. NatuTgeschichte der Thiere," 1797-lSOl, regularly cites the Deux Ponts edition. 

 Gmelin, in his " Systema Naturae," uses the original quarto edition.
